The Stages of the Four Stroke Combustion Cycle
The Intake Stroke
In this stage intake valve opens allowing air to mix with the gasoline inside the engine. The Piston at the top of the cylinder, moves down in order to this happen and allow in as much of a mixture as possible. The intake valve then closes which shuts in the mixture.
Compression
The piston now moves upwards to compress the mixture of gasoline and air together. (Compressing the mixture will make the energy released much more powerful.) The compression ratio for a diesel engine 20:1 whereas it is 8 to 10:1 for a petrol engine.
Combustion
The moment the piston reaches the top of the cylinder, a spark is released to ignite the mixture by the spark plug. As a result of this, the cylinder bursts driving down the piston, turning the crankshaft and powering the car.
Exhaust Stroke
This is final stroke in which the exhaust valve is opened and the burned gas from the blast is lead out of the cylinder into the tail pipe. This happens as the piston moves back to the top. This process is then continuously repeated.
